Actually, if you have a chance, use em as bait for bass fishing. They squirm a lot, and make all sorts of ruckuss when you hook em. They also stay alive after hooked for quite awhile. Just get on a canoe, troll the shores and drop your cidada off the side and I guarantee something will take the bait!!
They move so much the bass can't resist. Yellow and Black I imagine are all the more appetizing!
